The author who has the chance to make revisions not only before, but after his book has been printed is fortunate indeed. This new edition of Cubism and Twentieth-Century Art has afforded me just such an agreeable occasion. Although there have been no major alterations in the text, many minor corrections of fact, word, and interpretation have been made that I hope will increase the accuracy of this study as both history and analysis. In addition, the bibliography has been brought up to date. In accumulating a list of possible emendations, I am indebted to the helpful comments of many people. Of these, I should like to thank most particularly my friend and colleague, Edward F. Fry, who, though involved with the final preparation of his own documentary study of Cubism, was generous and patient enough to provide unerringly precise answers to my countless queries about matters of dating and bibliography.
